Airworthiness Directives; Eurocopter France Model EC130 B4 Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) Model EC 130 B4 helicopters, with certain twist grip assemblies installed, that requires inspecting the pilot and co-pilot collective levers for proper bonding between the twist grip drive tubes and the control pinions and if debonding is present, replacing the collective levers before further flight. This amendment is prompted by one incident in which the engine remained at idle speed although the twist grip had been turned to the flight position. The actions specified by this AD are intended to detect debonding between the twist grip drive tubes and the control pinions on the pilot and co-pilot collective levers to prevent loss of cockpit throttle control of the engine, and subsequent loss of control of the helicopter.

Which aircraft AD 2008-06-22 applies to

Applicability depends on the aircraft’s type certificate — check it against the specific tail.

Whether AD 2008-06-22 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 2008-06-22 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
